2. Differentiate between natural plant and animal fibers. How do they look different under a microscope?

3. Name four ways synthetic fibers are different from each other.

4. Draw a cross-section of a synthetic fiber and a natural fiber.

Some viruses can be crystallized and their structures analyzed. one such virus is yellow mottle virus, which infects beans. this virus has a single-stranded rna genome containing about 6300 nucleotides. its capsid is 25-30 nm in diameter and contains 180 identical capsomeres.if the yellow mottle virus begins its infection of a cell by using its genome as mrna, which of the following would you expect to be able to measure? a) replication rateb) transcription ratec) translation rated) formation of new transcription factors

Which of the following processes within viral replication is the greatest source of genetic variation in rna virus populations? a) high mutation rate due to lack of proofreading of rna genome replication errors.b) transcription from the host cell rna polymerase introduces numerous mutations.c) capsid proteins from the host cell can replace the viral capsid.d) viral rna is translated by host cell ribosomes.
